Application filed July 13, 1915. Serial No. 39,657.

an engine which can be quickly converted from a gas to a steam engine or from a steam to a gas engine.

An object of the invention is the provision of an engine having a rotary piston therein and a valve for controlling the supply of driving fluid to said rotary piston.

Another object of the invention is the provision of means cooperating with the feed or piston valve upon its upward stroke, after 7 it has sucked a charge of driving fluid into its casing, to release said fluid and allow it" to flow into the casing or piston cylinder for actuating the said piston.

A further object of the invention is the provision of an engine such as above described having a rotary piston therein containing spring-pressed sliding blades adapted to cont-act with the inner wall of the cylinder preventing leakage, and by virtue of the action of the driving fluid thereon, cause the rotary piston to rotate.

A still further object of the invention resides in the novel features of construction, formations, combinations and arrangements of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawings forming a part of this application, it being understood that various changes in the size, proportion and minor details can be resorted to within the scope of the appended claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings:

Figure 1 is a side elevation of the invention;

Fig. 2 is a longitudinal sectional view thereof;

Fig. 8 is a similar view taken on a different plane;

Fig. 4: is a transverse sectional view thereof;

Fig. 5 is a similar view taken on a differentplane;

Fig. 6 is a horizontal sectional view showmg the employment of a horizontal valve in connection with a vertical shaft.

Referring to the accompanyingdrawings by like characters of reference throughout the several views. and mrticularly the first five figures thereof, the numeral 10 denotes anengine base upon which is supported in any manner the cylinder 11. This cylinder 11 has a surrounding water jacket 12 spaced therefrom as at 13 forming a water space into which water or the like can be fed for the purpose of cooling the engine. I

A shaft 14: is cccentrically mounted longitudinally of the casing 11 and carries keyed thereon a rotary piston 15. This piston has diametrically opposed grooves 16 therein in which are slidably secured the outwardly spring pressed blades 17. Springs 18, seated in the grooves 16 and bearing against the lnner edges of the blades 1'4, serve to force the outer ends of the blades 17 against the inner surface of the cylinder 11.

An intake or manifold pipe 19 supplies the driving fluid tothe cylinder 11. is attached to an intake or supply casing 20 which has two compartments 21 and 22 therein. The former will be termed a feed compartment and the-latter a firing compartment. The upper side ofthe feed compartment 21 is provided with a valve seat 23 which communicates with the manifold pipe 19 through the openings 2%. A valve 25 normally closes, these openings 2-l. This valve 25 has a stem 26 which projects through the upper end of the compartment 21 and through the cooperation of the spring 27, yieldingly retains the valve upon its seat.

A piston 28 operates in the compartment 21 and upon downward movement sucks the driving fluid into the said compartment 21, unseating the valve 26. Upon the upward movement of the piston 28 the valve 26 is closed and the fluid forced into the firing compartment 22 which also serves the function of a compression chamber. A11 inclined intake port is formed in the walls of the casing 20 and cylinder 11 as shown by the numeral 29. This port 29 is closed by the valve 30, which has 21 depending stem 81 extending through the sleeve 32. A spring 33 surrounds the stem 31 and serves to normallv hold the valve upon its seat 34.

This pipe The piston 28 is operatively connected to a crank of the engine shaft l-l, while a cam 36 is formed upon the shaft 1% for engagement with the bearing hall 37 secured within the lower end of the valve stem 31. This connection is such that when the piston 28 completes its upward Stl'OliQ, the valve will he raised topermit the compressed driving fluid to flow through the port- 29 into the cylinder 11. This fluid will by its impact with the blades 1'? cause the rotation of the engine shaft 14. The device is so timed that each discharge of fluid into the cylinder will occur immediately in the rear of the blades 17.

When steam is used as a driving medium, the spar: plug 38 is omitted, but when the explosive medium is used, the spark plugs will ignite the same in the, usual manner in the rear of the blades 17.

The crank is formed upon a supplemental shaft connected to the main or engine shaft 14 by a suitable train of gears shown at 40.

AneXha-ust portll is provided in the lower side of the casing in such manner that tne spent gases will readily pass therethrough without clogging in the cylinder.

Referring to Fig. 6 of the drawing, the piston 42 rotates around a horizontal axis on the shaft- 43. The cylinder is shown at aid and communicates with the valve or inlet casing 45, through the intake port d6. The exhaust port of the cylinder 44 is provided with an exhaust port 47. A feed port a8 is provided in the casing 45 and connects with the valve controlled inlet %9. A rotary valve is mounted in the casing a5 and has a projection 51 formed upon one side thereof which prevents the driving fluid from leaking to the opposite side thereof. A spring pressed blade 52 projects from the Having thus descrioed the invention, what a I claim is:

in an engine, the combination of a cylinder having intake and exhaust ports therein, a shaft in said cylinder, a rotary piston car ried hy the said shaft, a casing adjacent the cylinder provided in its upper portion with communicating compartments, one of which compartments communicates directly with theintalre port of the cylinder, means for supplying driving fluid to the compartment= adjacent the one which communicates with the cylinder, a spring controlled valve in the compartment adjacent the one which communicates directly with the cylinder, a crank shaft operatively connected to the aforesaid shaft, means connected to the crank shaft for forcing the fluid delivered to said adjacent compartment mto and through the compartment which communicates with the. cylinder,

a spring controlled valve in the compartment which communicates with the cylinder,

and a cam upon the crank shaft to operate said valve.

In testimony whereof l affix my signature in presence of two witnesses.
